Surveys stopped to work overnight: Server error 500
I'm desperate because a survey stopped to work overnight. Now Joomla gives me a 500 server error regardless which survey I try.
Nothing changed at the Joomla! installation as far as I know. I tried to activate the error log in the Joomla! config and asked for the server logs from my provider. But actually I can't find any information that helps me to debug.
Please direct me on how to get the survey back online.
